Explanation:

Question 4

Step1: Set up proportion

Let \( x \) be the volume in ml. The proportion is \(\frac{20\,\text{mg}}{3\,\text{ml}}=\frac{10\,\text{mg}}{x\,\text{ml}}\)

Step2: Cross - multiply and solve

Cross - multiplying gives \( 20x = 10\times3 \). Then \( 20x=30 \), and \( x=\frac{30}{20}=1.5 \)

Step1: Set up proportion

Let \( x \) be the volume in ml. The proportion is \(\frac{5000\,\text{units}}{1\,\text{ml}}=\frac{10000\,\text{units}}{x\,\text{ml}}\)

Step2: Cross - multiply and solve

Cross - multiplying gives \( 5000x = 10000\times1 \). Then \( x=\frac{10000}{5000}=2 \)

Step1: Set up proportion

Let \( x \) be the volume in ml. The proportion is \(\frac{25\,\text{mg}}{2\,\text{ml}}=\frac{100\,\text{mg}}{x\,\text{ml}}\)

Step2: Cross - multiply and solve

Cross - multiplying gives \( 25x = 100\times2 \). Then \( 25x = 200 \), and \( x=\frac{200}{25}=8 \)

Answer:

\( 1.5\,\text{ml} \)
